How to synchronize time between OSX and Windows

Did you install a dual boot system which has one from Apple together with one from Microsoft?

And you find that the time is not properly synchronized between the two systems?

I think the more efficient way is to perform the solution on the Windows regedit. It's very simple.

( Changing the time zone in OS X does not turn out to be a permanent solution)

1) Boot into Windows

2a) If you are on XP, click Start, Run, then type regedit.exe

2b) If you are on Vista / Seven / Eight, click Start, then type regedit.exe in the search bar

3) Go and find this key: HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Control \TimeZoneInformation

4) Now right-click the mouse anywhere on the white space in the right area and create a new DWORD (32-bit)

5) Well, now you should name the new DWORD RealTimeIsUniversal

6) Double click on the new DWORD whose name is RealTimeIsUniversal and change the value of the DWORD from 0 to 1

7) Restart and boot into OS X. Set the correct time then boot back into Windows. Now, you have set the time of both systems correctly

8) End *** If you want to make the modification directly from OSX, install this pkg (by apple square). **** PKG not tested by me.

      Hi there.

      Previously, I installed Mavericks and Mountain Lion with Niresh's Distros and worked well!

      I did shrink like 50gigs of storage for Mac installation, created usb with the help of instruction, changed bios settings, and were ready to rock with dual boot support and every time it worked out without an issue! Though I had my old pc that time. 

      But I guess, from EL Capitan, things got messier a bit. Now I have to erase things and install mac first and then windows for dual boot.
      Also, I bought new pc, so whole bios settings are new to me.

      Conclusion : I need the latest Hackintosh with proper dual boot with my Windows 10, and I don't want to format nor erase anything on my HDD, and don't wanna format my windows 10. my father does work on this pc, me too, so please make sure nothing goes wrong, no file losing stuff please. I don't have other HDD so please I need the help. I want to install the mac on this existing windows machine. I could barely format windows 10 drive 'C' only and after mac, I will install windows again, but make sure except drive: C, no other drives get any effect at all. 

      And also, as I said, my PC is new, telling the specs of this pc, so please mention the bios settings and drivers stuff if possible. Please help me with Bios settings at least if drivers are not possible.

      Motherboard: MSI B250M PRO-VH
      CPU: Core i3 7100 (7th gen)
      RAM: HyperX 8GB DDR4 2400mhz
      HDD: 500GB SATA [GPT Partition]
      GPU: Nvidia 1050 TI 4GB
      Monitor : ASUS VP228 (1920x1080 Resolution)

      Another thing, I have ps2 keyboard, will it be ok? 

      Please help. Thanks.

      Hola de nuevo,
      No consigo arrancar el Windows 10, se me queda colgado en la ventana del icono de Windows.
      Alguien me podria dar algunos consejos a seguir para hacer que el bootloader funcione?
      He estado mirando, buscando, y todo lo que encuentro es para UEFI, en mi caso ( LEGACY), no encuentro nada ni nadie que este en la misma situación.
      Como he escrito anteriormente ( en otro post), no tengo nada de Clover ni de conocimientos, pero aprendo rápido si alguien me puede hechar un cable.
      Muchas gracias por todo.

      I wasn't sure which forum to use but since it's mainly about Mountain Lion, here goes...
      I have been using an ML Hackintosh for years and finally decided to set up Yosemite. I split the drive so I could install Yosemite in a new partition and still keep ML. I used Clover and the install went well, I'm using Yosemite right now. But when I reboot to use ML I have a problem - I didn't think ahead that Clover would be configured for Yosemite and not ML. Also, I was using Chameleon as a boot loader, which was configured for ML, but I obviously wiped that out when I installed Clover. So now when I try to start ML it gets stuck at "RTC: only sing..." and that's all I get. I can access the ML partition from Yosemite so I haven't lost any data, but I'd like it get a boot loader configured for dual booting. I don't know if Clover can do this - it seems like I'd need to set up an additional EFI partition for ML's use so maybe some of you Hack gurus and direct me on this.
      Also, Clover's boot loader screen is butt ugly! Are there themes or different backgrounds that can be used?
